The holy spear of the Thracian dragon kings, Gungnir is similar to Gáe Bolg, but it grants a bonus to Speed in place of Skill. Gungnir may only be equipped by users possessing major Dain holy blood, the only units to do so being Travant and Arion. No playable characters fulfill this requirement and it is unobtainable in the game.

Gungnir resurfaces in Fire Emblem Awakening, where its blood link has faded away, and it can be obtained and wielded by any playable unit with sufficient prowess with lances.

Travant later gives Gungnir to his son Arion in Chapter 9, who uses it against Seliph's army both in the same chapter and the Final Chapter to avenge his fallen father. Arion eventually turns against Julius in the Final Chapter when Altena speaks to him, after which he pledges to wield Gungnir for her sake.
